The James Webb and Nancy Grace Roman space telescopes are NASA’s latest flagship astrophysics observatories. One is in space already and the other will join it there soon. These two telescopes look very different, have different objectives, and together will advance our understanding of the universe. This four-part video series explores the differences and synergies of Roman and Webb.
Despite different observational strategies, both telescopes will be stationed in space at the Legrange Point 2, a relatively stable region a million miles away from Earth. From there, both will have an almost unobstructed view of the whole sky and low temperatures to keep their instruments cool.
Roman’s broad and enduring view will mesh perfectly with Webb’s focused gaze. As Roman discovers new wonders throughout the cosmos, Webb can follow up with detailed observations to help astronomers understand them better.
